Trying to use AndroidStudio (3.4.2) for the first time and it appers to be substantially different to the tutorial at
https://developer.android.com/training/basics/firstapp/building-ui
For example:
There is no layout editor toolbar let alone a show button.
There is no autoconnect button
It doesn't show any wiggly lines from the middle of the blue square to its edges.
When adding a text box it goes to the top left and can't be moved.
WTF is going on? This is awful!
So I know this may sound like the hard answer, but in the long run it will make life 1000x easier.
You need to learn XML to design the activities. It's fairly simple and really easy to research. The reason the textbox can't be moved is because the default layout is ConstraintLayout. In order to fix this, go to the xml file and change the Constraint layout to either Relative layout or Linear Layout. In the end, its more simple to learn straight xml.
I suggest you learn Android programming from here or somewhere else because the Android documentation can be confusing especially for a beginner like yourself and trust me, I've been there.
We want to attach some UI and other items to the back of the articulated hand. Just trying to figure out how to do that. I have found how to turn on and off the hand visualizer through MixedRealityHandTrackingProfile but I'm trying to find the Unity Game Object I can parent the items to or at least a way to access the hand transform. Thanks for any pointers!
Step 1: Select the object in the scene hierarchy that you want to follow your hand. Click “add component” in the inspector panel.
Step 2: Type in “RadialView” in the search box and you should see the RadialView solver appear. Click on it. You will see a few additional required scripts appear automatically.
Note: it adds the solver handler script. Along with that, the Radial View script will show up as well just like the orbital script.
Step 3: Change the radial view to not follow the head but follow the left hand. Select the dropdown menu next to the “tracked object to reference” option. Then select “hand joint left” from the menu.
Step 4: As you may see, once you select the hand joint you can choose which part of the hand you want the cube to follow. There are a lot of options to use! For this example, we are going to use the wrist. So next to the option “tracked hand joint” click the dropdown menu and select wrist.
Note: Not all joints, in this current version of the HoloLens2 can be tracked. This is a bug that may be fixed in the near future.
Now if you press play and try it out in your scene, you will see that the object does follow the wrist, but the object may lag a little bit behind and looks like it’s struggling to keep up. Now to fix this and make it so that the object is with the wrist at all time we must change a few things. Set the maximum and minimum distances to 0 so that the cube will not have any distance between it and the user’s wrist. Once set, the cube will be perfectly aligned with the wrist.
In the latest mrtk_development branch as of PR 4532 you can also used the "Hand Constraint" component. You can see an example of how to use it at MixedRealityToolkit.Examples/Experimental/HandTracking/Scenes/HandBasedMenuExample.unity.
Have a look at Assets/MixedRealityToolkit.SDK/Experimental/Features/Utilities/Solvers/HandConstraint.cs for the implementation.
You can add this behavior by adding a "Hand Constraint" solver to the object that you wish to follow the hand.
The Hand Constraint component will also be available in the upcoming MRTK V2.0.0 RC2 release.
I tried to use UMLDesigner to draw my project related diagrams. I see there is a Arrange functionality that can automatically layout diagram elements and links to save some manual work. But when i used it in my Activity diagrams it designed it upside down.
Here is an example. I created following simple activity diagram.
And here is how auto layout result for the same model looks like: auto layout.
The initial node is at the bottom and the final nodes are on top. But i want it the other way - to start at the top and end at the bottom. Is there a way to configure this?
I tried pinning starting and final nodes but it just made a mess after arranging the rest automatically. I searched the settings but couldn't find anything. I use UML Designer Version 7.1.0.
Thanks ahead for any help.
I am sorry there is no way from the preferences to change this behaviour.
This is because I never provide a specific layout for this diagram. Please, fill an issue in the bug tracker and it will be fixed for the next version of UML Designer as it is really easy to fix: https://github.com/ObeoNetwork/UML-Designer/issues.
Thanks for your feedback!
I am using UMLET to design the UML Sequence diagram for my system, i don't use the "all in one" option but the simple one dragging and editing the diagram components, so far so good, but i need to create an alt fragment with 2 or 3 guard conditions, i can't findd examples or documentation about it, the fragment component in the program doesn't show how to achieve my goal, could someone please help me?
You can create alt fragment with the interaction frame thingy in the palette.
Then in the diagram itself you can populate it with something like
alt
--
[x>0]
--
[x=0]
--
[x<0]
Note:
I would highly advise you against using this palette. Once you start making changes to it, it is a nightmare to manage as everything starts to misbehave — e.g. if you wanted to increase the space for [x=0] part, then you would add <enter> in the Properites window, however the messages and rest of the diagram will not move and you have to adjust it manually.
Not to mention that creating it manually this way is more time consuming.
So if you want to create sequence diagrams, you should either use the all-in-one palette, or other tool, such as PlantUML which has much nicer syntax (and looks better): http://plantuml.com/sequence.html
I have recently picked up Microsoft Office Visio 2010 in the interest of drawing out the execution flow of a software application I am planning. So far I have enjoyed the program, and it has helped me significantly to figure out exactly what interactions and events I will need for the program even before I begin coding it. However, there is one gripe I have with the software, as I add new elements to the diagram, Visio tends to try to combine routes as often as possible. This can make it difficult at times to see exactly where some of the routes are pointing. For example:
Example 1: Example 2:
In Example 1, You can see that there are three routes, each with a different label. Originally, these labels would overlap each other as well. I figured out this can be turned off in the "Page Layout" dialog, so it's a little better than it was, but the beginnings and ends of the route are still combined. Here it's not really an issue, but it could be as shown in Example 2.
What's pointing where in Example 2? The line coming in from the left is pointing at the diamond on the bottom, and then there are three routes coming out the top of the diamond. This is the problem I'm trying to solve. It's not shown in these examples, but putting labels on those three routes in Example 2 puts the labels all on that long stretch of vertical, which makes it impossible to tell which label corresponds to which line.
Is there a way to prevent the lines from overlapping like this? I have fully explored the "Page Setup" dialog, but none of the options available there seem to allow this behavior. The only solution I was able to find online was to draw all the routes manually, but this would mean I cannot use the "Re-Layout Page" feature, and it could be rather time-intensive if Visio decides to do it often.
Update: While messing around with some more settings trying to find a solution to this, I came up with a great example showing just how bad this can get. Now, this is an extreme example, and if your diagrams look like this you're probably doing it wrong, but it clearly shows that it can quickly become impossible to tell what the source and destination for each line is.
After many more hours of searching for ways to make routes either not overlap or play nice, the only solution I've found that keeps being recommended is to re-arrange the routes manually. Changing things like snap settings and page layout options do help to some degree, but not completely. Hopefully the next incarnation of Visio will handle this better. Oh well, it's still a great tool and has definitely helped me visualize execution flow.
This may not be the solution for you but in my network diagrams, I can perform the following.
In Visio 2010 click Design tab, now click Connectors, and select curved.
It separates the lines but again it might not look right for a flow chart.
I'm having the exact same issue and have not found a satisfactory solution.
I've tried all the permutations of snap/glue settings, layout behaviour and connector behaviour with no success.
The best solution I've found so far is to manually add multiple connector points to your source and destination and use those to connect your shapes. Make sure 'no overlap' is specified for your connectors. You can then use the automatic align/layout tools and get something reasonably unambiguous.
You do lose the benefits of dynamic glue but you can mitigate that by deleting connection points (ie from one side of a shape) to force Visio to use your custom connections. You'll also have to disable 'glue to geometry' in the snap/glue options.

Please update this question if you find a better solution.
Huh. Most of the time, I have trouble getting my lines to overlap nicely :).
You might try changing some of the Snap & Glue settings:
On the View tab, in the Visual Aids group, click the dialog box launcher (the little two-headed arrow). In the Snap & Glue dialog box, I'd try changing the Snap to setting for Shape geometry.
I cna't tell if you're talking about doing this from code or not, but I've found the Design -> Layout -> Re-Layout option takes care of this.
Similarly to Alex I've found adding my own glue points to shapes and removing the default ones helps enormously. So does making sure one has appropriate settings under Page Setup | Layout and Routing:
Style: Right Angle
Separate: All lines
Overlap: No Lines
Appearance: Straight
Spacing: I found all these distances especially important
Being aware of the setting for each connector under Developer | Behaviour | Connector | Reroute, how that setting changes from "Freely" to "On Crossover" when a connector is rerouted manually is also important. Sometimes I find it necessary to set a particular connector to "Never". Also useful is the ability to select all the connectors (and NOT the shapes) with Select by Type when forcing Visio to reroute.
I'm doing this with Visio 2013's ERD diagrams and I've noticed that whilst I have defined my own connection points now on each entity it is usually best not to actually select them but let Visio dynamically select the "best" one - then if I re-arrange the entities the re-routing still works. One curiosity I've noticed is that Visio's connectors do not align with my connection points at the bottom of each entity but (since I deleted the OotB connection point at the bottom of the entity at any rate) is spacing the connectors appropriately. Along the top and down the sides the connectors are dynamically attached in the same places as my connection points.
I still sometimes have problems with connectors being placed under/inside/through entities (so a connector running through/inside/under a shape) [with ERD's especially with self-referential relationships] despite Developer | Behavior settings on both the connector and the shape seemingly to prevent that. Those are often the ones I have to route manually and set to re-route "Never".
[Visio 2016]
Not a complete solution, just an aid to manual re-routing, ...
Add "Connection Point" to the two shapes. Each connection line will then have its own route, ... though some overlapping might still occur.
Being graphically challenged, here is how I accomplish it, ...
Select the one of shapes (I have to also zoom in to get better placement control).
Select the X in the [Home] menu bar.
The selected shape will have small bumps for any shape connection points.
Press and hold the Ctrl key and hover on the boarder of the shape, the mouse cursor will change to show where a point would be added.
Ctrl-Click to add a connection point. Here I added 10 or so points.
Add additional connection points to the other shape and move the connectors to use unique points on the two shapes. Your connectors will be (more or less) separated.
